... Finding 3.2: In the United States, the main federal agency responsible for RF health and safety is the FCC, with the FDA responsible for medical devices and radiation-emitting products. Finding 3.3: The RF exposure limits published by various organizations are similar to one another in terms of power density (W/m2)

... Finding 4.2: Previous reports applied various assumptions on how to measure and average the pulsed signal from an active AIT millimeter wave portal, which might explain some of the differences in their findings. Recommendation 4.1: The Transportation Security Administration should ensure that any future analysis of active portals are evaluated in a consis tent way and that the measurement methodology and the results are made available to the public in a clear and understandable way in relation to the applicable standards.

... Finding 6.2: The committee-led measurements at airports indicate that even at the entry position of the portal, the power density is several million times below the acceptable limit, even for a continuous signal. Finding 6.3: The committee finds that during normal operation of the ProVi sion ATD and ProVision 2 systems there is no risk to a person being screened to receive the applicable standard exposure limit of 10 W/m2; instead, the exposure is hundreds of thousands times less.

... Finding 7.8: The ProVision signal path can at best remain stable; any changes in the path can only cause further signal power loss, there is no way to alter the design inadvertently to produce an unintentional increase in the signal power. Finding 7.9: The ProVision signal power cannot be higher than during normal operation due to the system transceiver operating at full saturation.
